Bog Solution....JD? Taffy? Jetting? PN?

2 posts in this topic

I'm going to now tackle my low end "yamabog" issue. Looks like my choices for my '99 YZ400 are the

1. JD jetting kit

2. Taffy Mod

3. Change the jetting to 182 main, 50 pilot, and one needle richer

4. PowerNow

Anyway, anyone have any input to which one would solve the problem in the best manner?

well i had yamabog for a while and the power now really helped low end response but didn't completly get red of the bog the jd jet kit is what fixed it for me or you could just jet it right but the jd kit comes with all the mains so you can see what works for you but i think it came down to getting the fuel screw set exactly right
